Is corrosion contagious ? Will it spread to other pennies in the same container. Right now Im seperating them out but dont know what to do with them. Maybe a midnight run to the train tracks. Im going to try to use some solvent to clean them up. Any suggestions

Some people will say vinegar and salt. Or water and baking soda.
but that caked on green stuff really doesn't come off easily. |

| I tried the vinegar and salt idea. Does not work well on heavily corroded coins. I have baby food jar full. I have considered the Salvation Army pot. What do you think? Would they be offended with dirty money?? |

| Hydrochloric acid will react with any copper oxides, and most any other metal oxides, as well as zinc, but will not react with copper metal or nickel as far as I know. |

I agree with Kurr ... I've have used olive oil on several Lincolns (both copper and zinc) with excellent results. However, I haven't used o.o. on super heavy corroded cents. I would think that the more corrosion there is the longer you need to soak.
Have also used vinegar and salt, but that, IMHO, is pretty harsh and tends to leave evidence that it has been cleaned (etched?) with some sort of acidic material (vinegar).
I highly recommend olive oil. It was first recommended to me by a very reliable coin dealer who, except for olive oil, is very negative about any kind of coin cleaning (of course this would be for numismatics rather than copper hoarding).

One more thing ... 2old I think that's a wonderful idea ... giving the money to the Salvation Army. I doubt very much they would complain about dirty money  and they are just one of the worthy organizations to which even 'dirty' money is a worthwhile contribution.
Congrats on your idea!

Giving to charity is a fine idea, but dig into your pocket to do it. I think we need to kill these pennies. Execute them and plant them six feet under. They're plug uglies and will just jam our machines if they come back on another go around. We can't depend on the Mint to cull these puppies, that's a public service we can perform and it's only gonna hurt a few cents at a time. jmho  |
Hoard now and hold on!

| Salvation Army idea. After some consideration, I decided not to dump my crappy Zincolns on them, but gave them a few dollars instead. I am still not sure how to rid the world of them, but suggestions are appreciated. I do not want them coming around a second time. |

| I think that we penny people should take it upon ourselves to rid the world of this crap. No one wants it and since we have the opporutnity to see so many pennies, we should shoulder the burden. If I can rid the pennies of corrosion, I will, otherwise to the train tracks they will go. And this applies to ugly copper too. For God, my country and mankind, I shall rid the world of this scum. |

| I am curious about the original question that hasn't been answered yet. If you throw a corroded copper in a roll with regular coppers, will the corrosion spread around to other coppers it is in contact with? If so, how long will it take for one corroded penny to effect say a whole roll of coppers? |

so professor, where do we get this hydrochloric acid? I'm sure it's not sold to just anyone.

I am with mikep2020 ... I too would like to know if corroded copper will spoil good copper if kept in the same roll, bucket, jar, or whatever?
I do know that one spoiled apple will eventually ruin all the others in the basket/barel ... but not sure if 'living matter' follows the same set of rules as 'inanimate material'.

| I think it depends on how much oxygen is getting to these spoiled pennies. If they are mixed in a bucket with little 02 passing by, they should be okay. But this is just my 2 cents. |

| Go down to the hardware store and look for Muratic acid. That is Hydrochloric, just under a different name. Be careful when handling it, it is diluted for sale, but still highly corrosive. We use it in the shop to disolve hot dip galvanizing (zinc). If you nick the edes of a zincoln and submerge it, it will disolve the zinc core and leave you with a hollow paper thin copper cent. |

I concur with killerken53 - the muratic acid is like 30% hydrochloric acid. I've done the experiment of taking off the top layer of copper off of some zincs, then dumping them into the acid. Wow! Looks like Alka-seltzer in water! Yes, the copper is paper-thin afterwards. Be careful not to leave any copper in for too long - I did with some zincs and even the copper starts to break-down and turn ugly black!  And be careful! Do not inhale the fumes coming up from the reacting zinc and acid! I got a nose-full and wish I didn't! 
As for the corroded ones, I clean the common ones with some jewelry or silverware cleaner/rubbing compound (it has an ammonia-like smell) It takes off most corrosion, etc. Afterwards I throw them in with the hoard! I try to put some desiccant packs in with the larger jars/buckets to keep out moisture. I think moisture is the key element to keep out - not O2.
So I am not sure how effective the acid is with the 95% coppers. Experiment and see! |

| I think oxygen is the culprit hence the word oxidation. I believe that oxygen in any form is corrosive. So water, air, co2, probably are not good for any metal, except gold, which doesnt corrode. |
